Land Cruiser FJ40 biggest tire size: stock and lifted
The biggest tire owners run on a Toyota Land Cruiser FJ40 at every lift height, with the trimming it takes, the wheel specs you need and the lift kits that get you there.
The 'old tried and true' answer on IH8MUD is 31x10.50R15 on stock wheels and suspension. 33x9.50R15 is a popular size on stock 15-inch rims too, but owners report rubbing at the rear over bumps or at full flex. One fixed it with 1-inch spacers under the bump stops, and another had to adjust the front steering stops. One member said 33x10.50s looked 'pretty stuffed.'

Fresh springs and shocks fix the sag and harsh ride of 40-year-old leaves, and 2 inches clears 33s more comfortably. Greaseable anti-inversion shackles stop the rear shackle flipping over center.
Fitment comes from owners and specialists; wheel width, offset, trimming and bump stops change what fits. Check clearance at full lock and full flex before you buy. Some links are affiliate links.
